This D3.js (v6) scatter plot visualizes the Iris Dataset, mapping petal length and width for each flower sample while encoding species with distinct colors (purple, red, teal). The SVG rendering uses `d3.csv` to load the data, `d3.scaleLinear` for axes, and `d3.axisLeft`/`d3.axisBottom` for tick marks. Circular marks are positioned via `selectAll('circle').join('circle')` and labeled with rotated axis titles for petal length and width. The plot fills the browser window and includes a 24px tick font size for readability.
